How do contract law damages work?
Most people are aware when a breach of contract has occurred an award of damages could arise. But few know how damages are calculated by the courts.
Damages can be made up of various elements, some less obvious and less common than others. It is important for a party who has a claim for breach of contract against a defaulting party to consider any likely award of damages before issuing a claim. Our lawyers can check whether your claim is worthwhile.
Damages are usually awarded to an injured party for losses suffered as a result of the defaulting party’s actions or non-actions. The purpose of an award of damages for breach of contract is to put the injured party in the position it would have been in had the contract been performed.
Can you claim compensation in the UK for breach of contract?
Generally speaking the answer is no. English law is based on proving loss and subject to a few exceptions, it is not possible to claim pure compensation such as stress, inconvenience or injury to feelings after a breach of contract.
Can you claim damages for loss of opportunity?
In principle it is possible to include a loss of opportunity claim when suing for damages but in practical terms such claims are very difficult. This is because English law includes principles of causation (did the breach cause the loss) and foreseeability. In other words, it can be difficult to convince a court that future events, opportunities and benefits can be seen as linked directly to a breach of contract and were foreseeable
How to work out breach of contract damages
Consider the following steps when assessing damages :-
- When did the breach occur? – this is normally the date used for the assessment of damages.
- What is the financial loss caused? – this includes costs or liabilities incurred by the injured party to a third party. It also includes any profits which may be lost by the injured party as a result of the breach.
- What is the difference in value of the contract or the cost of cure? – often, the injured party can pay a third party to reinstate it to the position it would have been in had the contract been performed. This cost may be recovered by the injured party if the cost was incurred reasonably. A party can still receive damages even if a cure is not undertaken. Note, a claimant has to mitigate its loss, not aggravate it.
- Has loss been caused by extra time spent due to contract breach? – this may occur where the injured party’s staff had to investigate the breach or deal with the consequences of the breach. The injured party may recover its staff’s wages. However, this type of claim can be difficult to prove.
- Have goods been rejected or not delivered? – if a buyer of goods refuses to accept the delivered goods, refuses to pay for them or where the goods have not been delivered at all then the damages are presumed to be the difference between the market value of the goods and the contract price.
- Damages for defective goods? – the damages in this case would be the difference between the value of the goods at the time of delivery and the value of the goods had they not been defective.
- Has there been any mental distress or loss of amenity caused? – English law rarely allows damages of this type to be successfully claimed for contract breach. There are some exceptions such as where it can be established that an important object of the contract was to give pleasure or relaxation, for example a holiday. This type of award will be rare in commercial cases.
- Did the breach cause the loss? – this is a key question and a common area for mistakes by claimants. Not every breach can be legally proven to have resulted in loss and if a claimant cannot satisfy this test, notwithstanding a breach of contract, damages will not be awarded. The injured party must consider the position it was in after the breach and the position it would have been “but for” the breach – which of course is hypothetical.
- Have you mitigated your loss? -this means that the injured party has taken reasonable steps to avoid or reduce loss and has not acted unreasonably to increase loss. For example, if a supplier fails to deliver goods it will be necessary for the buyer to take all reasonable steps to find an alternative supplier at best price. If the buyer simply buys replacement goods from another seller at a much higher cost without investigating all options, this would be highly unlikely to be adequate mitigation of loss.
- Is the damage caused by the breach too remote? – the loss must be in the reasonable contemplation of the parties at the time the contract was made, i.e. it flows directly and naturally from the breach, or was reasonably foreseeable.
